There are two ways in which Moonstones can be added to your player profile.  

1. If you purchase Moonstones directly from your chosen game storefront, once the purchase is confirmed, you can go to your mailbox and claim your Moonstones. Once claimed, they will be added to your player account.

2. If you start your purchase of Moonstones from the Premium Shop, once the purchase is confirmed, the Moonstones will automatically be added to your player account.
